 注解是以键值对的形式给资源对象附加随机的无法标识的元数据。

<!--more--> 

<!--
The metadata in an annotation can be small or large, structured or unstructured, and can include characters not permitted by labels. Clients such as tools and libraries can retrieve this metadata.

注解中的元数据可大可小，可以是结构化的也可以是非结构化的，并且能包含标签不允许使用的字符。像工具和软件库这样的客户端可以检索这些元数据。
